Abstract
Background
During the last decade, a significant increase in the use of biologic medicine has occurred, accounting for the greatest healthcare expenditure, among inflammatory bowel disease (IBD) patients. The objective of this study was to analyse the prevalence of and time to first intestinal resection surgery in a Danish nationwide cohort of Crohn’s disease (CD) and ulcerative colitis (UC) patients, stratified on biologic treatment status.
Methods
This retrospective population-based study included IBD patients diagnosed between 2003 and 2015 identified in the Danish National Patient Registry (NPR). The frequency of first-time surgery with intestinal resection and time to surgery was analysed among CD and UC patients between 2003 and 2016.
Results
A total of 2328 CD and 2128 UC patients underwent surgery between 2003 and 2016 (23% and 10% of all incident CD and UC patients, respectively). Up until 2008, the frequency of surgery gradually declined for both patient groups and an increase in the frequency of patients receiving biological treatment was observed. Subsequently, the frequency of surgery for both CD and UC patients remained stable despite a steady increase in biologic treatment use.
Conclusions
The registered increase in the fraction of patients on biologic treatment (mostly TNF-α inhibitors) did not result in changes in the rates of major surgeries with intestinal resection in CD and UC patients.
